"This unique read--containing a boatload of likable characters and a few spine-tingling chills--plays out like a mystery movie on the big screen. The author really keeps readers guessing with each flip of the page--and it gets more and more exciting all the way up to the last chapter, which has the potential to make jaws drop." - RT Book Reviews

"Heartsick by Caitlin Sinead was a book unlike any other that I've read, which is saying a lot.... It was such a refreshing treat to read a book that was unique and hasn't been overdone or, as far as I know, been done before." - Lindy, A Bookish Escape

"This is Caitlin Sinead’s debut novel and all I can say is … wow." - Blueeyedcheery

Quinn is looking forward to her senior year at Poe University. She has big plans to hang out with her best friend, flirt with a certain boy genius, party at her favorite dive bar and figure out what she's going to do after graduation with her not-so-useful art major. But that's before she meets Luke, a hot townie who's moved back home to help take care of his dying sister. And it's before a weird epidemic sweeps across campus, mysteriously turning people's eyes purple.Is it an odd side effect from a new party drug?Is it a rogue virus developed in a campus lab?Is it the mark of the devil?Soon the town starts blaming the university and the student religious group becomes frighteningly aggressive in their on-campus accusations. Quinn and Luke are caught in the middle—until a tragic accident forces Luke to reveal the one part of himself he's kept carefully hidden. That he's so much more than the happy-go-lucky boy next door Quinn had believed him to be isn't a surprise…but this truth might be too dangerous for her to handle.

"HEARTSICK is destined to become a go-to example of great, speculative NA." - Carrie Butler, author of the award-winning Mark of Nexus series"A snappy, suspenseful plot balanced with stellar writing, brimming with chemistry and full of unique, nuanced characters. Quinn is the sort of strong, believable heroine I want to spend hundreds of pages with, and the mix of sci-fi-tinged mystery, small-town social tensions and a sweet-and-sexy love story kept me engaged until the end. Caitlin Sinead just made my auto-buy list."--A.J. Larrieu, author of Twisted Miracles
